Support for one liner conditional statement using ternary operator.

Does liquid js support one-liner conditional msg using ternary operator? e.g: I want to do something like this but it doesn't work.

{{ data.age == 18 ? 'You are under 18' : 'You are over 18' }}
OR
{{ data.age == 18 ? data.newVar1 : data.newVar2 }}

Unfortunately no. But I agree this would be a good feature, given all the discussions I see here: https://github.com/Shopify/liquid/issues/236

While the implementation would be changing the fundamental syntax, expect this feature won't come anytime soon. I'll leave this issue open for people to track.

@sanketdhoble Not sure if it helps, but I've generally used a custom filter similar to this in the past:

import { Liquid } from "liquidjs";

const engine = new Liquid();

engine.registerFilter("ternary", (value, truthyValue, falsyValue) =>
  !!value ? truthyValue : falsyValue
);
engine
  .parseAndRender('{{ data.age < 18 | ternary: "You are under 18", "You are over 18" }}', { data: { age: 8 } })
  .then(console.log); // outputs 'You are under 18'
